The correct way to use the gas switch valve is to turn it clockwise by 91 degrees and turn it counterclockwise by 91 degrees.

if the switch of the natural gas valve is in the shape of a ball valve, it means opening when the natural gas valve rotates 91 degrees clockwise, and it means closing when the natural gas valve rotates 91 degrees counterclockwise.

if the switch of the natural gas valve is wrench-shaped, it means opening when the natural gas valve is vertical to the natural gas pipeline, and it means closing when the natural gas valve is crossed with the natural gas pipeline.

if the switch of the natural gas valve is marked with the letters "s" and "o", when the natural gas valve is rotated to the position of the letter "o", it means opening, and when the natural gas valve is rotated to the position of the letter "s", it means closing.

Precautions for using gas

1. When using natural gas in the kitchen, be sure to open the window for ventilation to avoid some accidents. If the room is sealed, natural gas will produce carbon dioxide when burning, and the oxygen content will gradually decrease.

2. You can't just turn off the gas cooker and the gas valve in your daily life. It is suggested to close the valve in front of the stove before going to bed at night. When people go out for a long time, they should close the valve in front of the stove and the valve behind the table at the same time.

3. Especially when cooking with natural gas in the kitchen, be sure to be watched by someone. Do not leave without natural gas. If you leave the kitchen, turn off the gas stove and valve.

4. Pay attention to the repair and maintenance of the valve of the gas meter at ordinary times. If it is loose or the gas pipeline leaks, it must be repaired in time.

5. The gas connecting pipe should be replaced regularly. It has a service life. If it is some hoses, it cannot exceed two years. If it is found to be aging or cracked, it should be replaced, and there should be no winding problem when installing the soft pipe, otherwise it will easily damage the pipe.

6. Gas stoves also have a certain service life. If there is a problem, they need to be inspected and repaired. Moreover, gas stoves should be purchased from regular channels to effectively ensure the safety when using natural gas.
